H. W. GRAY. RAILROAD 0mm UNITED STATES HENRY W. GRAY, OF CLEVELAND,OHIO, ASSIGNOR TO HIMSELF, AND W. H. ALVORD, OF HOMER, NEW YORK.

RAILROAD-CHAIR.

Specification of Letters Patent No. 25,545, dated September 20, 1859.

To all whom it may concern.

Be it known that I, HENRY IV. GRAY, of Cleveland, in the county ofCuyahoga and State of Ohio, have invented new and useful Improvements inRailroad-Chairs; and I do hereby declare that the following is a fulland complete description of the construction 7 and operation of thesame, reference being had to the accompanying drawings, making part ofthis specification, in which- Figure 1 is a perspective view, Fig. 2 isa side view, Fig. 3 is a cross section, Fig. i is a top view, Fig. 5 isa view of the under side, Fig. 6 is a view of the grip, and Fig. 7 is aperspective view of a section of the chair.

Like letters refer to like parts in the several views.

The nature of my invention consists in such an arrangement of parts,that the two ends of the rails may be held firmly together and securedto the tie in the usual manner by spikes, and at the same time, tosupport the tread of the rail by means of flanges that rise upon eitherside from the base of the chair.

In the several figures, A A represent the railroad rails of the T form.

B 13 represent the chairs, two being required to form a seat. Thesechairs are made of wrought iron, and are swaged into a proper form,which form is generally represented in Fig. 7. One part of the chair,forms a horizontal plate or wing, upon which the bottom part of therails rest, as seen at a in Figs. 1, 5 and 7, and by the return of thechair around the edge of the rail, a longitudinal groove is formed,which embraces the two ends of the rail upon each side as seen at e, insection Fig. 3. From the top of the wing of the rail, the chair rises inan arch, inclining inward, toward the underside of the tread of therail, as seen at 0, so as to press firmly against the proj ecting part,or tread of the rail, thus giving additional support to the ends of therail, where they meet. The object of having that part of the chaircurved or arched, as seen at 0, is to give it greater lateral strength,and thus support more securely, the ends of the Ea ils, embraced betweenthem as shown in The width of the horizontal wings a, are such, thatthey very nearly meet upon the underside of the rails, as seen at E inFig. 5. The outer edges F, of the chairs B are made with a convexsurface, or are curved outward, or each end from the center being wedgeshaped, so that the distance upon the line X, X, in Fig. 5, is greaterthan at the ends of the chair as seen at K, K. The object of this, Iwill presently explain.

The two pieces forming the chair, are held in close contact with therails, by the grips C, as shown in various positions in the severalfigures, but detached and in perspective in Fig. 6. These grips are madeof good wrought iron, the form of which is shown in Fig. 6. After thechairs B, are properly adjusted to the ends of the rails, these gripsare slipped over the ends of the chairs and beneath them and the rails,each grip embracing one end of each section, as seen in Figs. 2, 4L and5. A piece of hoop or band iron D, of suitable width, is interposedbetween the convex surface F of each section of the chair, and the gripsare then driven snugly upon the chairs, the convex surface F upon eachacting as a wedge, and in this manner the sections of the chairs andrails are brought into close and firm contact.

When the grips have been driven as far as necessary to bring thesections of the chair in close contact with the rails, the ends of theband D are bent around as seen at (Z, in Fig. 1, and this holds thegrips firmly in place. The chair is now complete, and can be spiked tothe tie, in the usual manner.

These chairs can be removed and replaced at pleasure, without disturbingthe posit-ion of the rails.

lVhat I claim as my improvement, and desire to secure by Letters Patent,is-

Forming the railroad chair of two sections, having the outer surfaces Fconvex, as described, in combination with the grip C and band I), theseveral parts being arranged in the manner and for the purpose setforth.
